Why this synth?

The JUNO-106 combines digitally controlled oscillators with analog filters and amplifiers. Saw, pulse, sub-oscillator and noise form the starting sound. Sliders keep the controls approachable; programs store the settings.

Model & versions

This dossier covers the original hardware. The JUNO-6 and JUNO-60 are distinct models; the JUNO-106 includes MIDI and 128 program memories. The contemporary Roland Cloud version is software, not vintage hardware.
